Abstract:

The purpose of this paper is to determine how utilizing the three dimensional dynamic geometry software in teaching geometry and assessment learning domains of Prisms unit of the 6th grades’ mathematics lesson effects their spatial ability. The study took place in 2011-2012 academic educational years on thirty-four 6th grade students studying at a public elementary school located in Akyurt, Ankara. In the study, pretest – posttest control group experimental research model was used. While one of the 6th grades was determined as the experimental group, the other one was identified as the control group. The lessons were carried out with computer assisted teaching approach by using dynamic geometry software Cabri 3D on experimental group and with activity-based teaching method on control group as involved in the curriculum. In the study, “Spatial Ability Test” were used as data collection device. The data was analysed through a statistic program. At the end of the teaching process in which Cabri 3D is used, it has been seen that there isn’t any statistically significant difference between the experimental and control group students’ performance of spatial ability. The study results were interpreted in the light of the relevant literature
